I have also noticed this problem with faulty stack requesters.  It does not
always happen, and it never happens from a shell that was just opened.  It
seems that there is something funny about the way Lattice checks the stack.
I have taken to always compiling with the -v option.

I have also found a bug in _CXV25.  It was pretty simple, so I was able to
fix mine myself.  There are some pushes to stack that were left out, so when
the corresponding pops occur followed by an rts, you're in guru city.  I 
assume this bug was known.

Speaking of which, what is the phone # of Lattice BBS?  I seem to have
misplaced it.  Can anyone give a list of patches currently available for 5.04?
